gure 5-12 shows a customer-supplied power supply driving a current-sourcing PNP open collector
encod-er. Figure 5-13 shows how to power the same type of encoder from Flyer’s built-in +15 VDC power
supply.

Verify that eld wiring is correct after all encoder connections are complete using the Digital Scope ap-
plication (DigScope.exe in the WinMark folder). If the encoder is properly connected, inputs IN1 and IN2
should toggle as the position encoder rotates through its range of motion.
